Courier offers built-in 128- or 256-bit AES encryption and password protection to make it easy for you to secure your files. Use Courier's manual or automatic options to control the encryption process. Courier also wipes/shreds temporary files to ensure the security of attachments shared over email.
Convert files to PDF directly from Microsoft Office, including Word, Excel and PowerPoint. For extra protection, you can create a read-only PDF to deter copying. Courier also lets you add watermarks to your images to protect your work. For photos, resize high-resolution images to more convenient sharing sizes. Apply conversions as your attachments are zipped, or apply to a single unzipped attachment for instant sharing.
Get a look at the contents of incoming zipped attachments without having to extract files. In the Microsoft Outlook preview pane, simply click on the Zip file's icon to expand a list of its contents. You can also open/edit individual files directly from this list.
Apply watermarks, resize images and convert to PDF even if you choose not to zip your attachment. For example, you could add a watermark and resize an image to keep it within maximum message size restrictions without zipping, enabling your recipient to view the image immediately.
Insert shared links in Microsoft Outlook plain text messages and in the Outlook.com (Hotmail) "Edit in HTML" feature.
Duplicate files are common especially when sharing photos. Often two or more files have different names but identical content. This may be accidental or deliberate, but either way it increases the amount of information being sent and received. Duplicate file compressions detects when files are identical even if they have different names. It compresses only one of the duplicates into the Zipx file. It then makes it look like the rest of the duplicate files are also in the Zipx file. The result is a much smaller Zipx file but more important, the duplicate files can be unzipped as if they were in the Zipx file. You save time and space as do the recipients of your email.
Threads can get long and contain a lot of attachments. Finding a specific attachment in a long conversation can be annoying and time consuming. The "Conversation Attachment Manager" allows the user to see a list of attachments for the current email conversation they are reading. But seeing a list of attachments is only part of this feature's value. Additional value comes with the ability for the attachments in the list to be opened for viewing, saved to local or cloud storage location, zipped and saved locally or to the cloud, or encrypted and saved locally or to the cloud. With the Conversation Attachment Manager, finding that important attachment buried in a thread is much easier.
Courier's option to combine multiple PDF's into a single PDF has been enhanced. Now, Courier will also combine the files in the attachment that are converted to PDF into the single PDF file (if option to convert to PDF is enabled).
Sign your PDF files for added security. Previously available only when combining PDFs, you can now sign all your PDF attachments, including files that you have converted into PDFs.
